I purchased some bitcoins in 2011 from Dialcoin - I have an email I sent to them asking where the coins I purchased went (very naive at the time) - I've since sold the PC (which was also mining) to a friend (back in 2012)

Is there any way I can find the coins ?

I cannot remember the wallet I was using + had a piece of paper which I think I threw away a the time.

Please help.

David.
